A small focus library of basiliolides including basiliolide A₁, basiliolide A₂, basiliolide C and their structural analogues have been prepared for the structure-activity relationship study. The synthesis features a cyclopropanation/ring-opening strategy for establishing the C8 stereogenic centre by tuning the alkene geometry of the cyclopropanation substrates, IMDA for construction of the seco acid
为构效关系研究准备了一个小型的巴西利内酯库,包括巴西利内酯 A₁、巴西利内酯 A2、巴西利内酯 C 及其结构类似物。该合成具有环丙烷化/开环策略,用于通过调节环丙烷化底物的烯烃几何形状来建立 C8 立体中心,IMDA 用于构建 seco 酸衍生物和仿生 O-酰化用于前所未有的七元酰基乙烯酮缩醛环的形成. des-D-环类似物是通过 IMDA/脱羧策略制备的。此外,还开发了不对称催化环丙烷化,并为对称合成提供了富光学中间体。
